Bitmap: A table of digital BITS used to represent, for example, a picture or a text character, each bit in the table being interpreted as the presence or absence of a screen PIXEL or a printed dot. The principle can be illustrated by the following table, which represents the letter Z as a 6 x 6 table of bits:

1  1  1 1 1 1

0 0 0 0 1 0

0 0 0 1 0 0

0 0 1 0 0 0

0 1 0 0 0 0

1 1 1  1  1 1

Bitmap Editor: The generic name for programs, such as Adobe's PHOTOSHOP, whose function is to create and manipulate BITMAPPED images: that is files in which pictures are stored as a collection of individual PIXELS rather than as geometric descriptions. bitmap editor enables its user to change the colour of individual pixels or whole areas of pixels at once, using a variety of tools that mimic the effect of paintbrushes, pencils, spray cans and more. Typical bitmap editors also support a variety of graphics FILTER operations, such as EDGE ENHANCEMENT that can be applied automatically to the whole image.
